If you are wondering how to make your living space more comfortable and enlarge it, there are various options for you. For example, you can sell your existing space or order some remodeling procedures.

However, if you are not ready for such massive changes and interference to your existing structure, we are here to suggest a fantastic solution: an accessory dwelling unit creation. Accessory dwelling units (also known as ADUs) or granny unit is a smart decision for those who wish to make their primary residence bigger. The guide below will tell you about the essentials of building accessory dwelling units near your existing home and hopefully will answer all your questions. Do not worry: while “new construction” sounds like it is a complicated process that requires much effort, it is an exciting adventure, especially if you hire a team of talented workers.

ADU Builders Knights Landing, CA

Well, if you are planning to build your unit without any help from people who know what they are doing, believe us: it can become the biggest mistake in your life. You will probably waste all your money and even borrow some, and the property quality will be poor.

We are saying this not because we doubt your talents but because there are so many requirements for accessory dwelling units in California that you should comply with. It would be best if you find and hire a business that has proven its skills and has enough experience to meet your construction needs.

Such a business normally takes all responsibilities and completes your project from the very beginning to the moment when you walk around your unit and conduct your final inspection. It provides you with a wide range of services, permitting you to relax and calmly watch how the work is done day by day.

If you have never bothered yourself with seeking construction teams in your area that can help you with your ADU project and other property improvements, check our recommendations below.

ADU Contractor Knights Landing, CA

Choosing a contractor for your unit creation in Knights Landing might take some time — but you will not regret it in the end.

If you have no idea where to start, here are our suggestions for finding a team of builders that will be interested in implementing your construction plan:

Use word of mouth

Begin with searching among the people you know in person in Yolo county. Maybe one of your friends, coworkers, or relatives has recently completed a renovation or construction project? If so, they will tell you everything about the company they have worked with and provide you with precious recommendations.

Find online reviews

Besides talking to real people offline, you can check what online users say. Your aim is truthful reviews that sometimes can be negative. Thus, you will save yourself from hiring a company that provides poor services to the locals. Also, try looking for some photos made by clients in your area.

Talk to the company’s representatives

When you find a couple of candidates that might fit your needs, contact them and get more details about their work. Do they fulfill all permit requirements to work legally in your city? How many projects have they completed? How many years does the company exist? Do they have a portfolio with photos where you can see their works? These are the basic questions you should ask before signing an agreement with this or that entity.

Various companies in California offer their services related to accessory dwelling unit creation; among this wide variety, we have a company that will suit you well.

The A+ Construction & Remodeling company is an experienced market player that will be happy to build your dream unit and meet your budget expectations. Its team has specialists in engineering, architecture, and design that will provide you with the best service.

ADU Contractor Building Types

Let’s start with the types that you can select from when you think of creating an ADU close to your home. Each type serves different aims, so you have to define why you are building a unit in the first place. Then, when you understand the structure’s goal, you can easily choose a suitable type.

In California and Knights Landing, the most popular ADUs types are the following:

Attached unit

This unit becomes a logical extension of your house because it is connected to the primary structure with a wall and a door. It will work for you if you are having important family events like a newborn baby. The unit can be built instead of remodeling your space and adding another room.

Detached unit

A detached ADU is a separate property that has no connection with your existing place. Such a unit can be multifunctional, and you can use it as a home office for your remote days at work, as a guest house for your beloved friends, and as a temporary or permanent living space for your senior relatives who need additional care from you.

Junior unit

Among ADUs allowed, a junior ADU will probably be the smallest one, with a maximum size of 500 square feet. It is an affordable option for those who do not need much space in their units.

Converted unit

For an ADU, it is not necessary to begin new construction — you simply can convert an existing garage, pool house, or basement into a residential unit. Like a junior unit, a converted one does not require as much money as a detached or attached ADU.

Before you start your ADU project, ensure that you have chosen the proper type of your unit. Think all the points through and consult professionals regarding your situation. Every case is individual, and there is no better advisor than a professional contractor.


ADU Unit Construction Knights Landing

Additionally, you should know that building a unit in California does not mean that you simply plan and implement your project. Alongside planning, homeowners in the state have to get permits to build their structures.

There are also several requirements you should follow for your unit in Yolo county. That is why we always say that it is much better to hire a company like A+ that follows the trends and keeps track of various law changes in the accessory dwelling topic.

Requirements and rules are related to the accessory dwelling unit size, number of bedrooms and bathrooms, parking, setbacks, property lines, backyard, and other aspects.

For instance, your residential unit should have a minimum lot size of 150 square feet, but it cannot be more than 1000 square feet. If you neglect the rule and make the unit smaller than the minimum size according to the law, you might not receive a permit or have other unnecessary and inconvenient consequences.

So, it does not matter which unit type you choose; in any case, you’d better hire someone who knows the topic and can provide you with a well-built structure that complies with local laws and regulations. The A+ ADU builder guarantees that every building it has constructed is legal, whether it is a commercial building or housing.

Benefits of ADU Building

ADUs are great add-ons to multi-family properties and single-family homes. Accessory structures have several benefits that you might not realize before you order and build one of them.

Here are the most obvious benefits you get when your unit is done:

Existing space enlargement

If your problem is a lack of space and constant arguments with your family, an ADU will be a delectable property enlargement that will let you and your family members breathe freely and build harmonious relationships.

Also, do not forget that you can use an ADU as your home office. When the COVID-19 pandemic started in 2020, many workers switched to the remote regime. Having a separate room or even unit to spend your work day in a quiet space is precious.

Multifunctional property

An ADU becomes a property that you can use for different tasks and events: yesterday, it is your home office, today you spend time with your hobbies there, tomorrow you host a party and invite guests who stay in the unit, and so on. With a smartly furnished ADU, you can do lots of things under one roof.

Additional income

You can rent your ADU and get your investment return every month. This typically works for a detached or a junior unit because they stand separately from your primary property.

An investment in your future

If you ever decide to sell your house and land plot, having an ADU will allow you to put a higher price on your offer.

As you can see, ADUs significantly improve properties, and many homeowners in California choose to build such units near their houses. All you have to do is find a reliable ADU builder for your project.

  • Frequently Asked Questions

    How can I find a contractor in California for my ADU?

    Nowadays, it is rather easy to find a reliable company that will help you build your unit. You can ask someone you know for advice or use the internet to see numerous reviews and comments from locals that will assist you in decision-making. Also, it is important to check each company’s portfolio to ensure that you are making the right choice.

    Is it expensive to build such a unit in California?

    It is hard to estimate the cost of your future unit without knowing the details. The price depends on the size of your unit, the materials and furniture you use, and many other factors. However, the average cost for a unit in California is 200,000-300,000 US dollars. Remember that there is a prefab unit option that can be more affordable.

    Why should I hire a company in California for my ADU instead of using a DIY approach?

    Hiring specialists who are aware of all building and engineering aspects is much better than developing a project on your own. Firstly, because you will have to get a permit for your unit, and cooperating with a specialist who will help you with that is the best, it will speed up the process significantly. Secondly, only professional builders will ensure that your unit will stand on your land for dozens and even hundreds of years. By hiring a company, you avoid plenty of risks that DIY builders meet. So, we recommend you follow our recommendation and find a local business that will build a unit for you.
